Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Example 1
the embodiment provides a production plan generating method, which can be applied to terminal equipment with a display function, where the terminal equipment includes, but is not limited to, a personal computer, a smart phone, a tablet computer, a desktop or all-in-one machine with a camera, and the like. The production plan generating method may also be applied to a hardware environment formed by a terminal device and a server connected to the terminal device through a network, where the server may be a common server or a cloud server. The network includes, but is not limited to, a wide area network, a metropolitan area network, or a local area network, among others. The production plan generating method of the present embodiment may be executed by the server, the terminal device, or both the server and the terminal device. For example, for a terminal device that needs to generate a production plan, the production plan generating function provided in this embodiment may be directly integrated on the terminal device, or a client for implementing the production plan generating method provided in this embodiment may be installed. For another example, the production plan generating method provided in this embodiment may further run on a device such as a server in the form of a software development kit, and an interface of a production plan generating function is provided in the form of the software development kit, so that a terminal device or other devices may implement the production plan generating function through the provided interface.
fig. 1 is a flowchart of the production plan generating method, which includes step S101 and step S103.
Step S101, obtaining original order data and existing raw material data, wherein the existing raw material data comprises names of existing raw materials and numbers of the existing raw materials.
specifically, the original order data is order data determined according to the customer requirements, including but not limited to the name of the product, the number of the product, the delivery date of the product, and the like. The original order data can be input into the system by a dispatcher through input equipment such as a keyboard, a touch screen or a remote controller, and the order data input by the dispatcher is received through the input equipment, so that the original order data is obtained. The original order data can also be imported from other information systems and databases of the enterprise, for example, the original order data can be obtained from order management, sales management, ERP and other systems. Further, the existing raw materials include a stock-in raw material that is a raw material existing in the warehouse and a fixed raw material that has been purchased and has a purchase delivery date before a schedule date. For example, if the procurement delivery date of the predetermined raw material a is 2 months and 18 days, the scheduled date is 2 months and 18 days later. The existing raw material data can be input into the system by a dispatcher through input equipment such as a keyboard, a touch screen or a remote controller, and can also be directly obtained from the raw material management system in a scene with the raw material management system.
Step S102, according to the situation that the quantity of the purchasable raw materials is unlimited, determining a first producible order according to the original order data, the existing raw material data and the purchasable raw material data, wherein the purchasable raw materials are raw materials with a purchase lead period smaller than the interval from the current date to the scheduling date, and the purchasable raw material data comprise the names of the purchasable raw materials and the quantity of the purchasable raw materials.
The purchase lead time refers to the total time from the purchase order to the raw material purchase and storage. The data of the purchasable raw materials can be input into the system by a dispatcher through input equipment such as a keyboard, a touch screen or a remote controller, and can also be directly obtained from the raw material management system in a scene with the raw material management system. The procureable raw material is a raw material with a procurement lead time smaller than the interval from the current date to the production schedule date, for example, for the procureable raw material B, if the procurement lead time of the procureable raw material B is 10 days and the current date is 2 months and 1 day, the production schedule date is 2 months and 11 days later.
The original order data includes a name of a product and a quantity of the product, a kind of raw material and a quantity of the raw material required for producing a product can be obtained by splitting the product according to parts constituting the product, and an order that can be actually produced, that is, the first producible order can be calculated from the existing raw material data and the purchasable raw material data. For example, the original order data includes 100 pieces of product a, and 3 pieces of raw material C and 4 pieces of raw material D are required to produce one piece of product a, and if the total number of existing raw material C and purchasable raw material C is 180, and the total number of existing raw material D and purchasable raw material D is 450, the order that can be actually produced is 60 pieces of product a, that is, the first producible order is 60 pieces of product a.
Step S103, planning and scheduling the first producible order to generate a first production plan, and determining starved material data according to the raw materials required for completing the first production plan and the existing raw material data.
specifically, the first producible order is allocated to each production unit according to the capacity of the production unit such as each production line, each team or each machine, so as to generate the first production plan. The planning and scheduling for the first producible order can be implemented by using an existing planning and scheduling algorithm, which is not described herein again. Comparing the raw material required to complete the first production plan with the existing raw material, and removing the existing raw material from the raw material required to complete the first production plan, i.e., obtaining missing raw material, wherein the missing data includes a name of the missing raw material and a quantity of the missing raw material.
In the method for generating a production plan according to this embodiment, the purchasable raw material is a raw material whose purchase lead time is less than the interval from the current date to the scheduled date, so that production can be organized in advance by using the existing raw material, and after the procurement department carries out procurement according to the shortage data, the lacking raw material is called to continue production, so that production of the existing raw material can be accurately scheduled when procurement is not determined, and a production plan can be scheduled for a shortage order to be procured in advance, thereby shortening the order delivery cycle and improving the productivity utilization rate under the shortage condition.
In an alternative implementation manner, after performing step S101, the method further includes: determining a second producible order from the raw order data and the existing raw material data; and planning and scheduling the second producible order to generate a second production plan. The second producible order is determined in a manner similar to that of the first producible order, and the second production plan is generated in a manner similar to that of the first production plan, which is not described herein again.
With the expansion of production scale, many enterprises set up or outsource a plurality of factories for the same type of production and manufacturing business, for discrete manufacturing enterprises, the production links are more, the process is more flexible, and when the production capacities among the factories are similar or the same, the factories can jointly complete some production tasks, no matter the same product is produced respectively or the front and back processes are cooperated, so that the production plan of the multiple factories can not stay in the primary stage of distributing orders and then producing the orders respectively, but the whole plan is completed on the basis of considering the transportation logistics cost, time and the like, so as to achieve better plan production scheduling effect. Thus, in an alternative implementation, for collaborative production between multiple factories, the planning and scheduling the first producible order to generate a first production plan includes:
splitting the first producible order according to production processes to obtain a production task corresponding to each process;
according to the types of the parts which can be produced by each production unit of each factory, distributing the production task corresponding to each procedure to each production unit, and constructing an objective function taking the production task corresponding to each production unit as an unknown number;
And solving the optimal solution of the objective function, wherein the optimal solution of the objective function is the first generation plan.
Specifically, the original order data includes names of products and quantity of the products, each product is composed of a plurality of parts, the generation of the parts and the assembly of the products both involve a plurality of processes, and dependency relationships exist among the processes, so that the first producible order can be split according to the production processes to obtain the production task corresponding to each process. According to the parts which can be produced by each production unit of each factory, such as a production unit of a production line, a team or a machine, the association relationship between each production unit and the type of the parts which can be produced by each production unit is established in advance, and the production task corresponding to each process is distributed to each production unit according to the association relationship. When the task allocation is carried out on each production unit, an objective function with the production task corresponding to each production unit as an unknown number is constructed, and the objective function can be one or more of an order aging function, a production cost function, a transportation cost function and an inventory cost function. If the target function comprises the order aging function, determining the transportation aging between factories in advance, and determining the order aging function according to the transportation aging between the factories and the production task corresponding to each production unit; if the objective function comprises the transportation cost function, the transportation cost between factories needs to be determined in advance, and the transportation cost function is determined according to the transportation cost between the factories and the production task corresponding to each production unit. And solving an optimal solution of the objective function, namely solving the optimal solution which enables the order to be maximum in time effectiveness, the production cost to be minimum, the transportation cost to be minimum and the inventory cost to be minimum, wherein the optimal solution is the first production plan. Furthermore, since the multi-factory collaborative production requires the transportation of parts between factories, the transportation allocation command can be generated according to the difference of the production quantity of the parts in each factory between the front and rear processes.
production manufacturers often receive relatively urgent orders or temporarily modify orders in business, which often require rapid response. For general production enterprises, modification and verification are difficult after a production plan is issued, and only spare capacity and materials can be allocated to a new order on the basis of the original plan, or plan quantity can be simply modified for a modified order. However, the emergency new order is often produced, the production line still produces the non-emergency order according to the original plan, and the spare capacity materials are not redistributed and utilized after the order is modified. Therefore, in an alternative implementation, after performing step S13, the method further includes:
obtaining new order data according to the original order data and the order change data;
taking the new order data as the original order data to generate a new production plan;
Judging whether the new production plan meets preset requirements or not;
And if the new production plan meets the preset requirement, executing the new production plan, otherwise, modifying the new order data, and regenerating the new production plan until the new production plan meets the preset requirement.
specifically, the order change data includes, but is not limited to, changed items, product names that need to be changed, and product quantities that need to be changed. For example, the modified item may be to increase order size, decrease order size, modify product delivery, and the like. Similar to the original order data, the order modification data may also be entered into the system by a dispatcher via an input device such as a keyboard, a touch screen, or a remote control. And after the order change data is obtained, correspondingly changing the original order data according to changed items to obtain the new order data. And taking the new order data as the original order data, and executing the step S12 and the step S13 to obtain the new production plan. And for the new production plan, judging whether the new production plan meets the preset requirement, wherein the preset requirement can be that the production cost is lower than the preset cost, the production benefit is higher than the preset benefit and the like. And if the new production plan meets the preset requirement, executing the new production plan instead of executing the first production plan, otherwise, modifying the new order data, such as modifying product delivery time, product quantity, product priority and the like, executing the step S12 and the step S13 again, and regenerating the new production plan until the new production plan meets the preset requirement. It should be noted that the new production plan may be obtained by a newly added simulation plan scheduling module, or may be obtained by an actual simulation plan scheduling module, which is not limited in this embodiment. Through simulating order modification, the capacity materials can be globally coordinated, the resource utilization rate is maximized, and the feedback results of whether the order is successfully adjusted or not and the predicted delivery date are obtained in real time.
